Dr. Marco Singer, Head of Fragrance Performance at the Symrise AG, kicked off the first workshop day with an excellent keynote address on how to objectively measure the performance of
fragrances with a focus on longlasting, malodour reduction and blooming effects of fragrances.

In the following, Björn Maxeiner, director and head of P&M testing at Olfasense, provided a holistic overview of the possibilities in sensory and molecular odour testing and the most
important principles to follow to achieve the highest possible quality standards.

One of the key elements of successful odour testing is the selection, training and monitoring of the noses in question, as Olfasense expert Dr. Nathalie Nibbe highlighted in her presentation,
which also provided useful insights on the challenging setup of a GC sniffing panel to meet the stringent requirements of this sophisticated methodology.

The first workshop day was rounded off by a first round of different practical lab exercises, to provide skills, encourage participation and exchange information on topics, such as sampling
& preparation, olfactometry, panel training, direct odour evaluation, comparative testing, indoor room evaluation, molecular screening, GC sniffing, and more.

We were glad to welcome another external expert as a keynote speaker of the second workshop day. Thomas Wortelmann, managing director of the GC-IMS specialist G.A.S. Dortmund, provided
insights on trace gas analysis of volatiles using Gas Chromatography - Ion Mobility Spectrometry in different applications, especially product quality control.

Subsequently, Olfasense GC specialist Dr. Luciano Vera gave a vivid presentation on the multidimensional nature of odour chemistry and olfactory perception and demonstrated how GCMS and GC
sniffing can provide approaches to overcome this challenging complexity.

Before the participants could again get active in the second round of practical lab sessions, Lieke van Genderen, consultant at Olfasense B.V., took the audience on a short excursion to the
neuroscience of smell and visualised in case studies how research is acquiring new insights on how our brain reacts to odour.

The event was concluded by fragrance and flavour expert Dr. Hansruedi Gygax (Gygarome) who shared fascinating facts about the human sense of smell in his closing address “Visualisation and
quantification of odours: From concepts to meaningful measurements”.
